Abstract：As one of the low-lying-land countries, the Netherlands is well known for its low elevation and flat topography, which makes it prone to floods and storm surges of the North Sea. After experiencing many flood disasters, the flood management strategies in the Netherlands have changed from construction of flood control projects at the early stage to flood risk management. Taking Dordrecht as a concrete example, the multi-layer flood risk management strategy of the Netherlands is analyzed in detail. Specifically, the first layer is flood prevention, the second layer is sustainable land use planning, and the third layer is disaster emergency management, which form a coordinated approach to effectively mitigate flood risks. Since China's flood storage and detention areas (FSDAs) are facing similar problems as Dordrecht, we learn from their successful experience and put forward four practical suggestions for FSDAs: (1) develop flood prevention (flood diversion) standards based on both the cost-benefit and flood risk analysis; (2) adopt flood resilience measures according to local conditions so as to improve the flood resilience of critical infrastructures in FSDAs; (3) carry out flood risk zoning in FSDAs, propose a zoning application solution and explore multiple development models in each zone; (4) take the construction, application and development of FSDAs into consideration, and carry out comprehensive management of FSDAs.
